At high temperatures, quantum chromodynamics (QCD) exhibits a deconfined state of matter
known as the quark-gluon plasma (QGP).[1]}, [2]}
The nature of the degrees of freedom of the QGP, however, remains largely unknown.
By studying this state, we seek to understand how complex behaviors arise from QCD,
including how strongly-coupled systems and their bulk properties emerge from quantum field theory.
